Hi Bob -
Even though we no longer have our
EggCamper - I still enjoy visiting from time to time ;-)
Our current camper also is without a screen, but opens from the bottom/hinged at the top like your
EggCamper. I came across this newer style window made today, which has a screen, lever locking bar that also acts to prop out the window. I think we could emulate this design and make it work. A velcro attached screen and a prop 'stick' might do the trick? It would sure be nice to have extra fresh air especially during rainy weather ;-)
I have attached a couple pix of a window with the screen and lever latch - other is a close-up of the lever style latch, for your review.
